Preserving Alpha Channel for FCP?

Hi,
I'm trying to use a logo, made by our graphic artist in Final Cut, only when I go to it has a white background. When I view it in Photoshop I can see through to the checkered background, so I am assuming the alpha channel is present.

I've tried re-saving it and that causes the background to turn black.

The PSD is a school logo with only has one layer.

Any idea what I need to do to be able to use the logo and still get the alpha channel, or where the problem might lay?
